The Group

We first entered the sintered based tungsten market in 1948, since then we have been working hard to develop and broaden our skills and expertise.

Our advanced technology enables us to control the entire production process, from refining minerals to the micro-finishing operation.

Thanks to the knowledge and the stable ownership of the Tedeschi family, we are proud to be an independent player in the global market.

We are highly motivated to meet any challenge the market presents, with a mission of fulfilling all customer expectations.
